Gluten-Free Diet Craze: Booming

Grocery stores are packed with gluten-free products--the U.S. Department of Agriculture estimates that gluten-free revenues will reach 2- billion dollars this year.

Why the sudden explosion of gluten-free products?

The answer may come from the University of Pavia where Italian researchers find that unfounded benefits of going gluten-free are rampant.

Baylor-Plano licensed-registered dietitian Megan Moore said for those who are not gluten-intolerant it's become a fad diet.

Moore is often peppered with questions about the benefits of a gluten-free diet.

"Usually they've heard about it on the internet, they've had a friend who started a gluten-free diet and there is a lot of marketing,” Moore said. “But there is really no scientific evidence that eating a gluten-free diet is going to help anyone if you don't have celiac disease."
